Abstract: From the theoretical point of view of the flow mechanism in packed beds of cylindrical bodies, a generally valid equation for the pressure drop was derived. Its general validity concerning the influence of the void fraction, the Body dimension di/da and the tube wall D$_{h}$ was investigated by pressure drop measurements. The semi-empirical relation obtained between the dimensionless pressure drop, the Reynolds number and the geometry data is valid for 10$^{2}$ < Re < 10$^{5}$ , 0,34 < $\Sigma$ < 0,82, 0 $\le$ di/da < 0,85, 6 < D$_{h}$/d$_{v}$ < 24. Measured data for the void fraction of packed beds of solid an hollow cylinders are given. The influence of the uncertainty in the void fraction an the pressure drop is represented quantitatively by means of an error calculation.
